Abstract

The present invention relates to a multistage fiber filtering apparatus capable of selectively filtering depending on turbidity of raw water, in which a first filtration mode where the raw water passes through a fiber ball medium, a second filtration mode where the raw water passes through a fiber yarn medium, or a third filtration mode where the raw water passes through both of the fiber yarn medium and the fiber ball medium may be selectively operated.
